Definitions

  • the present invention relates to a pond pump with a housing, with a suction port, which is associated with a through-slots suction portion of a housing shell, with a pressure port which is in fluid communication via a pump disposed in the housing means with the suction port, with a motor for driving the Pumping device and with a control device for controlling the pumping device and the motor.
  • Such pond pumps are well known in the art such as out DE-A-100 43 668 , They are positioned at the bottom of a pond or basin.
  • the housing of the pond pump is designed as a coarse filter and has slots through which water can penetrate into the housing, but not leaves, small branches and other coarse particles.
  • the water is sucked by a pump disposed in the direction of the pump into a behind the coarse filter shell suction port and pressed via a pressure connection in a pressure line, which emits the water at a free end.
  • a pump for regular cleaning only water from the bottom of the pond or basin is sucked. With such a pump, it is not possible to suck in water from the pond surface to clean these too.
  • the object of the present invention is therefore to provide a pond pump, with the water at a given intake volume can be optionally sucked from the bottom of a pond or pool and / or from the water surface thereof.
  • the intake port is additionally associated with an intake manifold, which is arranged adjustable in relation to the intake port, such that a suction volume of the intake port to the intake manifold and the intake is divisible.
  • a suction pipe can now be attached to the pond pump, which ends in the upper part of a water level, so that water can be sucked in from this area, wherein the intake volume of the suction as needed distributed to the bottom area of the pond and the water surface can be.
  • Another advantage of the present invention is that the intake manifold between a first end position and a second end position is adjustable, wherein in the first end position, the proportion of the intake volume at the intake 100% and the intake is 0% and in the second end position, the proportion of the intake volume at the intake port 0% and at the intake is 100%.
  • the intake manifold and the intake port are arranged with a longitudinal axis in a plane and the intake manifold is rotatable about a rotational axis perpendicular to the longitudinal axis between the first end position and the second Endpositon.
  • the pond pump can be built in a very compact manner. Due to the rotation of the intake, the setting of the intake volume can also be visually recognized from the outside.
  • another advantage is that the longitudinal axes of the suction port and the intake manifold coincide in the first end position and enclose an angle in any other position between the first end position and the second end position.
  • the pressure connection also has a pressure port for connecting a pressure line, which is the case regularly, the angular position between the pressure port and the intake manifold also changes by the adjustment angle. So that the setting is visually noticeable even from a distance.
  • a pond pump 1 is shown schematically.
  • the pond pump 1 has a housing 3, the upper housing shell is designed as a filter cover 3.1.
  • the filter cover 3.1 has small openings or slots 3.2, which serve as a coarse filter. From the periphery of the housing 3 are a discharge nozzle 5 and an intake 7 before.
  • a pumping device 9 is arranged inside the housing 3, which is of conventional design and will not be described further here.
  • the so-called subsonic, also small openings or slots 3.2 are formed as a coarse filter. Through these openings or small slots 3.2 and water can be sucked from a pond, so that these openings and small slots 3.2 on the housing 3 form a suction, which also gets the reference number 3.2 assigned as synonymous below.
  • an electric motor 11 is arranged waterproof.
  • Fig. 3 is a plan view of the pond pump 1 without filter cover 3.1 is shown schematically.
  • a suction port 17 is formed in fluid communication with the pumping device 9.
  • a pressure port 15 is formed with the discharge port 5.
  • the suction port 17 and the pressure port 15 each have a longitudinal axis, which lie in the present embodiment in a common plane. In an operating position of the pond pump 1, this common plane is preferably a horizontal plane. In other embodiments however, this plane may also be a vertical plane in operation or a plane between a horizontal and a vertical plane. It is also conceivable that the two longitudinal axes of the suction port 17 and the pressure port 15 are not in a common plane.
  • the intake manifold 7 is adjustably arranged in the housing 3 with respect to the intake port 17.
  • the intake manifold 7 is in a second end position, which brings the intake manifold 7 from a fluid communication with the suction port 17.
  • the suction port 17 sucks 100% of its intake through the intake or the slots 3.2 of the filter cover 3.1 and the lower shell.
  • the intake manifold 7 can be brought continuously or via intermediate positions in the end position shown in Fig. 4.
  • the pumping device 9 sucks 100% of the intake volume via the suction port 17 and the discharge port 7. In this first end position in Fig. 4, no water is sucked through the intake area 3.2.
  • Fig. 3 and Fig. 4 it is shown that the intake manifold 7 is rotatable on a circular path about an axis of rotation which is perpendicular to the longitudinal axis of the intake manifold 7.
  • the suction volume of the pumping device 9 can be distributed to the intake manifold 7 and the slots 3.2 of the filter cover 3.1.
  • the intake volume of the pumping device 9 can be adjusted via the intake between 0% and 100%.
  • the respective difference of the intake volume to 100% is then supplied via the intake area 3.2.
  • Fig. 5 the pond pump according to the invention is shown schematically and in perspective from the side. On the right side in FIG. 5, the intake slots 3.2 and the intake area 3.2 formed by them are shown.
  • FIG. 6 shows a plan view of the pond pump 1 from FIG. 5.
  • the plan view from FIG. 6 is somewhat more detailed than the plan views from FIG. 3 and FIG. 4.
  • the intake stub 7 can also be adjusted stepwise.
  • latching points 19 are formed in FIG. 6, on which the intake manifold 7 can be positioned.
  • the intake manifold 7 has a thread 21, preferably an external thread, to which a suction line can be connected.
  • the pumping device may be provided with an antifreeze device (not shown) which protects it from freezing.
  • the discharge nozzle 5 has a thread 23, preferably also an external thread on which a pressure line (not shown) can be connected.
  • a cable connection 25 is provided for an electrical supply line.
  • the included by the intake manifold 7 and the discharge nozzle 5 angle is in the first end position, that is, at 100% intake through the intake manifold 7, 90 °.
  • the angle between the discharge nozzle 5 and the intake manifold 7 in the second end position is between about 90 ° and 180 °.
  • the angle of the intake manifold 7 with respect to the longitudinal axis of the intake port 17 is in the first end position 0 ° and in the second end position about 0 to 90 °.
  • Fig. 7 is a system sketch is shown, which shows a pond cross-section.
  • the pond pump 1 according to the invention is positioned.
  • a pressure line 35 is attached, which leads to a pond filter outside the pond.
  • a suction pipe 37 is attached, which leads to a skimmer 47 in the region of the water surface of the pond.
  • the intake of soil dirt can optionally be varied between 0 and 100% of the total pump power. Accordingly, the Suction of surface dirt can be varied between 0 and 100%.
